Introduction to chemistry

Chemistry is a branch of science that deals with the analysis of material and the substances that comprise it. It also manages the properties of these substances and their reactions to form new substances. It is basically centered on particles and atoms that make up components and mixtures. These chemical species will in general connect using bonds.
